[Elecraft] Car-Starter battery packs

[Lynn W. Taylor, WB6UUT]

Just bought a second one of these.

Like UPS batteries, starting draws a ton of current all at once.  The 
intended use will limit the life of the battery.

I have a Bolt Power D28, which has two USB charging ports, and an outlet 
that can be different voltages from 12v to 19v -- it'd run a laptop 
nicely for quite a while.  The supplied "laptop" cable would power a KX3 
nicely.

The Bolt D29 has more capacity, but doesn't have the "laptop" power.

I paid about $60 each on Amazon (on sale).

The D29 is 18 ah, the D28 is 13.6 ah.

We've actually used the smaller one to start a car.

73 -- Lynn
